Perpendicular lines intersect to form four right angles. never always sometimes
natima [27]

Answer:

Always

Step-by-step explanation:

The definition of a perpendicular line is that it intersects another at a 90 degree angle. Using this, by verticals, the opposite corner angle must also be 90-degrees, and since one side of a line is 180 degrees, 180-90 = 90, which ensure the rest of the angles will be 90 degrees too.

Solve C = 2πr (solve for "r")<br> C = 15
Jobisdone [24]
C = 2 pi r

but c = 15

15 = 2 pi r
15 = 2 * (22/7) * r
r = (15*7) / 2 / 22
r = 2.386

Find 50% of 36:<br> Find 25% of 36:<br> Find 75% of 36:
HACTEHA [7]

Answer:

18, 9, 27

Step-by-step explanation:

36 ÷ 2 = 18. Dividing by 2 is the same as multiplying by 50%.

36 ÷ 4 = 9. Dividing by 4 is the same as multiplying by 25%.

Since 25% • 3 = 75%, you can do 9 (from previous) • 3 to get 27.

Write the equation in slope intercept form. what are the slope and y intercept?
VMariaS [17]

Option C  

<u> Answer: </u>

The equation in slope intercept form is -\frac{5}{12} x-\frac{11}{12}

The slope is -\frac{5}{12} and y-intercept is -\frac{11}{12}

<u>Solution: </u>

The slope - intercept form equation of line is given as

y = mx + c    ---- eqn(1)

Where m is the slope of the line. The coefficient of “x” is the value of slope of the line.

c is the y – intercept which is the value of y at the point where the line crosses the y-axis

From question, given that -5x - 12y = 11 --- eqn (2)

On converting equation (2) in slope – intercept form, that is adding 5x on both sides,

-5x - 12y + 5x = 5x + 11

-12y = 5x + 11

Now on dividing -12 on both sides,

y=-\frac{5}{12} x-\frac{11}{12}     ---- eqn (3)

Comparing the given equation (3) with equation (1), we get  

m = -\frac{5}{12} and c = -\frac{11}{12}

Hence Option C is correct.
